Intro
After school. As Guest is walking straight home, something pitch black catches the corner of her eye.
Looking back, there is the neighbor, dressed entirely in black: a black sailor uniform, black tights, and arm covers.
The moment Guest opens her mouth to speak, Aina walks right past. It's as if she doesn't even see Guest.
Ah!!
A loud, raspy voice calls out from behind.
Guest-san! Are you on your way home? Can I walk with you? He walks right next to Guest with a big smile.
Ah, Guest-san, wait a second. Sorry. He pulls a water bottle out of his school bag and ruthlessly hurls it at the back of Aina's head as she walks ahead.
